Nanocomposite Copt:C Films For Extremely High-Density Recording, M. Yu, Yi Liu, A. Moser, D. Weller, David J. Sellmyer

David Sellmyer Publications

Nanocomposite CoPt:C films were investigated as potential media for extremely high-density recording. An annealing temperature of over 600 °C is necessary to form nanocomposite CoPt:C films consisting of C matrix and fct CoPt nanocrystallites with grain sizes of 8–20 nm and coercivities of 3–12 kOe. Coercivity and grain size increase with increasing annealing temperature and decreasing C concentration and they are insensitive to film thickness. The average activation volumes are about 0.9×10^-18 cm³. The properties of these nanocomposite CoPt:C films can be tailored to satisfy the thermal stability, coercivity, and media noise requirements for extremely high-density recording.

(Teff,Log G,[Fe/H]) Classification Of Low-Resolution Stellar Spectra Using Artificial Neural Networks, Shawn Snider, Yuan Qu, Carlos Allende Prieto, Ted Von Hippel, Timothy C. Beers, Christopher Sneden, David L. Lambert, Silvia Rossi

Publications

New generation large-aperture telescopes, multi-object spectrographs, and large format detectors are making it possible to acquire very large samples of stellar spectra rapidly. In this context, traditional star-by-star spectroscopic analysis are no longer practical. New tools are required that are capable of extracting quickly and with reasonable accuracy important basic stellar parameters coded in the spectra. Recent analyses of Artificial Neural Networks (ANNs) applied to the classification of astronomical spectra have demonstrated the ability of this concept to derive estimates of temperature and luminosity. We have adapted the back-propagation ANN technique developed by von Hippel et al. (1994) to predict …

Secondary Reproductive Strategies In Pacific Black Brant (Branta Bernicla Nigricans), Pamela A. Svete

Biological Sciences

Waterfowl are known to use secondary reproductive strategies, both extra-pair copulations and intraspecific brood parasitism, to increase fitness. We used five polymorphic microsatellite loci to determine extra-pair paternity and nest parasitism in 30 nests of Pacific Black Brant geese (Branta bernicla nigricans) containing 108 offspring. Fourteen of the 30 nests contained offspring that were not genetically related to one or both of the attending adults: 6.5% (7/108) of the offspring resulted from extra-pair copulations (EPC); 13.9% (15/108) of the offspring resulted from intraspecific brood parasitism (IBP). All offspring resulting from EPCs were produced during the peak period of nest initiation. …

Putative Pheromones In The Urine Of Male Moose: Evolution Of Honest Advertisement?, Chris Linda Whittle

Biological Sciences

I tested hypotheses about how olfactory communication is related to mating behavior in Alaskan moose (Alces alces gigas). Males dig rutting pits where urine is deposited to which females strongly respond. Consequently, male urine may contain primer pheromones that synchronize estrus of females. Urine samples were collected from captive moose on the Kenai Peninsula, Alaska. Samples included those from the mating season and from the nonrutting period for two adult males, one yearling male, and one male and one female calf. After pH adjustment, samples were extracted with methylene chloride to yield 3 fractions (acidic, neutral, and basic), which were …

Acute Toxicity Of The Oil Dispersant Corexit 9500, And Fresh And Weathered Alaska North Slope Crude Oil To The Alaskan Tanner Crab (C. Bairdi), Two Standard Test Species, And V. Fischeri (Microtox Assay), Sara Louise Rhoton

Marine Biology

Toxicity assays of the oil dispersant Corexit 9500, and fresh and weathered Alaska North Slope (ANS) crude oil were conducted on Alaskan tanner crab larvae (Chionoecetes bairdi) under cold-region conditions, the reference species, Mysidopsis bahia and Menidia beryllina, and Vibrio fischeri (Microtox bioassay). Acute 96-hour toxicity data for C. bairdi were calculated using the response 'affected' (decreased phototactic response and ability to swim). C. bairdi were most sensitive to non-dispersed weathered oil (EC₅₀=0.4 mg/L), least to dispersant-only solutions (EC₅₀=1,267 mg/L), and were typically more sensitive than the reference species. Dispersant-only solutions were consistently least toxic for all species tested. Dispersed …

Studies On The Ecological Physiology Of Porphyra Abbottae And Porphyra Torta (Rhodophyta): Development Of New Species For Mariculture In Alaska, Jan Marie Conitz

Fisheries

Environmental factors affecting the distribution and growth of Porphyra abbottae and Porphyra torta were studied in a research project on the feasibility of nori mariculture in southeast Alaska. In situ abundance of Porphyra abbottae was compared at sites in Sitka Sound, Cross Sound and Chatham Strait. Growth of laboratory cultured Porphyra torta gametophytes was studied in response to nutrients, salinity, crowding and substrate. The seasonal progression of abundance in Porphyra abbottae varied between study sites, with associated differences in water motion and temperature. Double sampling techniques improved accuracy of in situ abundance estimates. Germination and initial growth of cultured Porphyra …

Nonprofit Welfare-To-Work Programs: A Study Of The Programmatic Factors Related To Success For Single Tanf Women In Readiness Programs, Kathy Guidi

Master's Theses

This research project was a qualitative study with data collected primarily through interviews with three constituencies of welfare-to-work job readiness programs: TANF (Temporary Assistance to Needy Families) clients, nonprofit agency staff, and Department of Human Services (DHS) CalWORKs Department employment specialists. Specifically, six TANF clients, six nonprofit agency staff, and two DHS CalWORKs Department employment specialists were interviewed by the researcher. The study was conducted to determine which programmatic factors were related to success for single T ANF women participating in nonprofit organizations' work readiness programs in San Francisco. Program factors were divided into four areas: program model/structure, program curriculum, …

Wavelength-Specific Fluorescence Coefficients For Simulating Hyperspectral Reflectance Signatures Of Water, Charles R. Bostater, Jan Rebman

Ocean Engineering and Marine Sciences Faculty Publications

A model1'2 which describes the transfer of irradiant light in water is used to predict the fluorescence response ofthe water surface reflectance under solar induced or an artificial light source such as a laser. Formulations for the estimation of wavelength dependent fluorescent coefficients. The techniques allows the description ofa fluorescence reflectance response in deep and shallow waters with various bottom reflectance signatures such as submerged vegetation, corals and sand. Recent advances in the model are presented for obtaining wavelength dependent fluorescence spectrum responses from the solutions of the two flow equations following the procedures developed by Bostater1'2'3. Synthetic or modeled …
